# APPENDIX 8-G. REBUTTABLE PAYBACK ANALYSIS RESULTS

8-G.1 INTRODUCTION

This appendix contains the cost and effici ency tables described in chapter 8. DOE

based the payback periods on the calculati on methodology found in the DOE room air

conditioner and clothes dryer test procedures; these payback periods may differ from

those found under field conditions.

8-G.2 ENERGY CALCULATIONS

8-G.2.1 Room Air Conditioners

The energy consumption in the LCC analysis is determined using the DOE test

procedure. The DOE test procedure calculates annual energy consumption, E annual 

# , as

follows:

= Capacity × ( Hrs / 1000 ) / IEER E

annual



# Where:

Capacity = room air conditioner input capacity,

Hrs = room air conditioner operating hours (750 hrs), and

IEER = room air conditioner efficiency.

8-G.2.2 Clothes Dryers

The energy consumption in the LCC analysis is determined using the DOE test

procedure. The DOE test procedure calculates annual energy consumption, E annual 

# , as

follows:



# E

F 

# = Cycles × ( Lbs / IEF )

Where:

Cycles = clothes dryer cycles per year, cycles/yr, (416 cycles/yr),

Lbs = pounds of clothing, lbs, (7 lbs for standard and 3 lbs. for compact

dryer) and

IEF = clothes dryer efficiency.

8-G.3 RESULTS TABLES

Tables 8-G.3.1 to 8-G.3.10 show the re buttable payback period calculation results

for each product class.
